BEURER MG40 INFRARED MASSAGER

£29.99, stressnomore. co.uk CLAIM: The head of this massaging device vibrates and heats up using infrared radiation. The maker says it can be used to treat aches and tension, circulatory disorders and fatigue. EXPERT VERDICT: ‘There has been good research into how massage and heat increase blood flow. This can ease sore muscles,’ says Gary Jones.

‘But it won’t heal a muscle injury. Years ago there was a suggestion that infrared therapy would help tissue healing, but there’s been no good clinical research to support this. ‘I would steer clear of this device in the early stages of an injury as heat will make the pain worse over the initial three to five days. ‘It may even delay the recovery, as increased blood flow will lead to more pain and swelling.’
